Methods and apparatus for fast starting and loading a combined cycle power system are described. In one example embodiment, the method includes loading the gas turbine at up to it's maximum rate, and loading the steam turbine at its maximum rate with excess steam bypassed to the condenser while maintaining the temperature of steam supplied to the steam turbine at a substantially constant temperature from initial steam admission into the steam turbine until all steam generated by the heat recovery steam generator is being admitted to the steam turbine while the gas turbine operates at up to maximum load.

A rotary engine includes a rotor with a plurality of working surfaces. Each working surface of the rotor includes a recess covered by an insulating plate. A ledge is formed within and part way around a periphery of the recess and across one end of each recess. A slot extends into the rotor adjacent the other end of each recess. The plate is supported by the ledge and has one end fixed to a corresponding end of the recess. The other end of each plate is slidably received in the slot so that the plate is spaced apart from a bottom surface of the recess, thus forming an insulating air space or chamber between the plate and the body of the rotor. A small vent through the plate prevents pressure changes within the chamber from deforming the plate.

The lubricant metering system is for a rotary piston mechanism of the Wankel type and provides for by-passing a predetermined amount of lubricant past the oil seal ring carried by the rotary piston. The by-pass is one or more radially extending recesses of small total flow area in the contact surface of the oil seal ring, each of the recesses being in the nature of a scratch.

A container and a lid for a container or container is provided. The container includes a lid and container body to which the lid is attached. The container may further include a storage compartment attached to the end of the container body. The lid includes a lid body defining a drinking aperture providing access to a central cavity of the container. The lid includes a snap closure pivoting relative to the lid body between an open position permitting fluid to pass through the drinking aperture, a first closed position with a portion of the snap closure is only biased against, but not engaged with, the lid body to prevent fluid to pass through the drinking aperture and a second closed position wherein the snap closure is engaged with the lid body.
